Abstract

An object of the present invention is to provide an electromagnetic wave shielding light diffusion sheet having good electromagnetic wave shielding ability and being capable of emitting uniform diffused light which has a lot of transmitting light and few dispersion of brightness. The present invention relates to an electromagnetic wave shielding light diffusion sheet which is formed by laminating a translucent electrically conducting layer having a surface resistivity under 10<SP>5</SP>Ω/□ on at least on face of light diffusion sheet body.
